It is not uncommon in the nature for insects to have symbiotic relationships with microorganisms. The bean bug, Riptortus pedestris, which harbors symbiont Burkholderia sp., is a serious agricultural pest in South Korea and Japan. It is reported that the symbiont has positive effects on the fitness of R. pedestris. However, virtually no information is available for how this insect finds the symbiont in the nature and how the behavior of R. pedestris is affected by the symbiont. To investigate the symbiont acquisition mechanism, the frequencies of R. pedestris approaching to symbiont or untreated control treatment were compared in a plastic cage (465×290×260mm) (n=20). In the experiment, there was no detectable difference between the two treatments. Further study using video tracking systems will help us to better understand detailed behaviors for symbiont acquisition.
